Yeah the room is like a meta-cabinet.
Your speaker strategy has to consider listening style (sitting, working, watching, ambient, etc.) and build from there: big stereo, small nearfield, flooded or point source, placement like height angle and and close or far to wall, audio style, resonance locations, materials in and on surfaces, etc..
So two big towers or a bunch of wee little Kantos can be great or lousy depending on all that.
Or you could just buy a couple of cheap pure silver speaker cables coated with gold and everything will be great.
Every successful political resistance includes a healthy protest movement. It is necessary.
May I add that while the whole world is dealing with a surge in authoritarian bullshit, the particular case of the USA is going to require much more than just a shift in the political roster. The problem is deeply cultural, as evidenced by the hollywood style approach of so many armchair tacticians. Start there, and work on you and yours while also taking direct action.
